本文是地质矿产部自1978年~1987年十年来组织开发金矿化探工作的一篇总结性和评述性文章。该部十年来采用化探方法发现的金矿产地共272处,其中现已查明为工业矿床者62处。总结的主要经验有:①努力实现用痕量金作指示元素来寻找金矿床;②金矿化探工作中应坚持“区域展开,重点突破”原则;③全矿化探普查的选区应以1:20万区域化探中出现的金异常为依据;④在金异常检查和详查中采用痕量金的“现场分析”方法。对于金矿化探在我国今后的发展趋势作者提出如下看法:①金及有关元素的区域性地球化学图件的编制和研究预期将加速开展;②痕金分析方法和技术将获得进一步发展,并提出应研究和开发一种可以同时测定Au、Ag、As三种元素的现场分析方法和技术;③金矿化探的采样代表性问题的研究将被列入议事日程;④金异常的检查和研究将普遍开展;⑤厚层覆盖地区金矿化探方法的研究将获得重要进展。
This article is a summary and review article organized by the Ministry of Geology and Mineral Resources for the work of geochemical exploration of gold from 1978 to 1987. A total of 272 gold deposits were discovered by the Ministry over the past 10 years through the use of geochemical exploration methods, of which 62 have been identified as industrial deposits. The main experience summed up are as follows: (1) Trying to find the gold deposits by using trace elements as indication elements; (2) Adhering to the principle of “regional expansion and key breakthroughs” in gold and geochemical exploration work; (3) : 200,000 regional gold in the geochemical anomalies based; ④ gold anomalies in the inspection and detailed inspection of the use of trace gold “on-site analysis” method. The authors put forward the following views on the future development trend of gold mineralization in China: (1) The preparation and research of regional geochemical map of gold and related elements are expected to accelerate; (2) The method and technology of gold analysis will be further developed and It is suggested that an on-site analysis method and technique that can simultaneously determine three elements of Au, Ag and As should be researched and developed. Thirdly, the study on representative sampling of gold geochemical exploration will be included in the agenda. Research will be carried out universally; ⑤The research on gold mineralization and geochemical exploration in thickly covered areas will make important progress.
